We're dividing 2951520 by 648 
We want to divide 2951520 by 648.

Going ahead to step 1:
648 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 648

Moving on to step 2:
648 goes into 29 0 times with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Include the next digit (5) from the dividend after 29, then repeat: 295 / 648

Advancing to step 3:
648 goes into 295 0 times with a remainder of 295.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 295 and we're left with 295.
Bring next digit (1) of the dividend behind the 295 and repeat the process: 2951 / 648

Moving on to step 4:
648 goes into 2951 4 times with a remainder of 359.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 2592 away from 2951, we end up with 359.
Take the next digit (5) from the dividend and append it to 359, then repeat: 3595 / 648

Step 5:
If we divide 3595 by 648, we get 5 and a remainder of 355.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtracting 3240 from 3595 leaves us with 355.
Fetch the next digit (2) from the dividend, attach it to 355 and continue: 3552 / 648

On to step 6:
648 goes into 3552 5 times with a remainder of 312.
The number 5 becomes the next digit in our result. 
Result so far: 455.0
Deduct 3240 from 3552 and we're left with 312.
Fetch the next digit (0) from the dividend, attach it to 312 and continue: 3120 / 648

Going ahead to step 7:
648 can be fit into 3120 4 times, resulting in a remainder of 528.
The next digit of our result is 4. 
Result so far: 4554.0
Deduct 2592 from 3120 and we're left with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 8:
The number 648 fits into 5280 8 times, leaving a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 4554.8
Subtracting 5184 from 5280 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 9:
The number 648 fits into 960 1 times, leaving a remainder of 312.
Use 1 as the next digit of our solution. 
Result so far: 4554.81
If we subtract 648 from 960, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 10:
The number 648 fits into 3120 4 times, leaving a remainder of 528.
Write down 4 as next digit of the result. 
Result so far: 4554.814
If we subtract 2592 from 3120, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

On to step 11:
When dividing 5280 by 648, we get 8 with a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 4554.8148
If we subtract 5184 from 5280, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 12:
648 can be fit into 960 1 times, resulting in a remainder of 312.
Use 1 as the next digit of our solution. 
Result so far: 4554.81481
If we take 648 away from 960, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 13:
648 can be fit into 3120 4 times, resulting in a remainder of 528.
The number 4 becomes the next digit in our result. 
Result so far: 4554.814814
The remainder is 528 after subtracting 2592 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 14:
648 goes into 5280 8 times with a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 4554.8148148
Deduct 5184 from 5280 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 15:
When dividing 960 by 648, we get 1 with a remainder of 312.
Use 1 as the next digit of our solution. 
Result so far: 4554.81481481
Deduct 648 from 960 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

In conclusion, the division gives 4554.81481481 with a balance of 3.12e-07.
